Question

Изгорода в противоположных направлениях одновременно выехали два автомобиля.Скорость одного из них 80км/ч а другого 75 км/ч.На каком расстоянии друг от друга будут автомобили через 4 ч? РЕШИ ЗАДАЧУ ,ОБРАТНУЮ ДАННОЙ!!!!!!

Answer 1

80+75=155(км/ч)-V отдаления
155*4=620(км)

Answer 2

1) 80*4=320(км/ч)-скорость первого автомобиля
2)75*4=300(км/ч)-скорость второго автомобиля
3)320-300=20(км)
Ответ:20(км)

Answer 3

Problem Analysis

We have two cars moving in opposite directions. One car is traveling at a speed of 80 km/h, while the other car is traveling at a speed of 75 km/h. We need to find the distance between the two cars after 4 hours.

Solution

To solve this problem, we can use the formula: distance = speed x time.

Let's calculate the distance traveled by each car after 4 hours.

Car 1: - Speed: 80 km/h - Time: 4 hours - Distance = 80 km/h x 4 hours = 320 km

Car 2: - Speed: 75 km/h - Time: 4 hours - Distance = 75 km/h x 4 hours = 300 km

Now, let's find the distance between the two cars. Since they are moving in opposite directions, we can add the distances traveled by each car.

Distance between the two cars = Distance traveled by Car 1 + Distance traveled by Car 2 = 320 km + 300 km = 620 km.

Therefore, the two cars will be 620 km apart after 4 hours.

Answer

The two cars will be 620 km apart after 4 hours.
